Some of our integration tests for the MongoDB Realm functionality seems to be quite flaky.

This is especially true for EmailPasswordAuthTests. One example here https://ci.realm.io/blue/organizations/jenkins/realm%2Frealm-java/detail/PR-6895/1/pipeline

The error manifests as `ACCOUNT_NAME_IN_USE(realm::app::ServiceError:49): name already in use` which indicate that somehow our test users are not being correctly deleted after each test, but attempts to verify this in https://github.com/realm/realm-java/pull/6848 has so far failed.
